I’ve been wrestling with this idea.
- God is the only absolute, necessary being (all confessional Christians agree to this).
- That which is not absolute is contingent.
- Human choices are not absolute, thus contingent (2).
- There is both necessity and contingency (1, 3).
Is that the same thing as “free will?” It is probably not the same thing as libertarian free will, nor have I covered all of the finer points. I think the propositions stand, though. All of this is another way to affirm the necessity of consequence and the necessity of the consequent thing.
